Eight years into the Great Depression, timber workers had had enough. Their work days were too long, their wages were too low, and their living conditions were squalid. They went on strike in January 1937 and again in October, and their peaceful organizing won union recognition, higher wages, better conditions, and a central role in regional and national timber worker movements.

Timber workers had attempted to organize before 1937, but their efforts at collective bargaining were unsuccessful. Large-scale logging in Minnesota began in the mid-nineteenth century, and workers tried to organize for better conditions almost immediately, beginning in 1858. But without union support, spontaneous strikes were ineffective.

For many decades, established unions like the American Federation of Labor (AFL) refused to organize timber workers. Men who worked in the logging industry were typically single and had to move from camp to camp as the logging industry's needs changed. Only the most militant labor organizations were willing to work with such men. The largest timber worker union drive before 1937 was led by the International Workers of the World (IWW) in 1916 and 1917, but it was violently repressed.

As logging conditions worsened in the 1930s, labor agitation was sweeping the United States. In 1934, Teamster truckers led a major strike in Minneapolis, and Midwestern strikes among steel and auto workers followed in 1935 and 1937. In 1936, Minnesotans overwhelmingly elected the Farmer-Labor candidate, Elmer Benson, as governor.

The first timber strike was called on January 4, 1937, and 4,000 workers walked off the job. Logging companies were caught off guard, and the strikers had leverage. If they did not finish skidding logs along the icy roads before spring temperatures melted the ice, the logging companies would lose that season's harvest. The logging companies had to settle quickly.

The strike was settled peacefully by the end of January, and the timber workers won many of their demands. Timber producers officially recognized the union and promised eight-hour workdays, wages of $70 per month, and better living conditions.

Union leaders were not content to organize just the state's workers. In March, Timber Worker Union president Fred Lequier announced a regional strategy: in order to keep their gains, Minnesota timber workers would help to organize lumberjacks in Michigan, Wisconsin, and Canada.

In May, timber workers from Michigan went on strike, led by Minnesota organizers. But in Michigan, large logging companies with vast resources still dominated the timber industry. They were able to organize vigilante squads that violently attacked strikers, including Duluth labor lawyer Henry Paull, who was beaten severely and dumped in Wisconsin. The strikes were called off, and workers' demands were not met.

By the fall, attention turned back to Minnesota, where the January contract was ending. This time, the logging companies were prepared. In April, 85% of Minnesota logging companies had come together to form the Minnesota Timber Producers' Association (MTPA). The MTPA orchestrated a public relations campaign to damage the second major Minnesota strike. MTPA members tried to drive a wedge between poor farmers and poor timber workers in northern Minnesota.

Despite these efforts, many farmers wrote to Governor Benson to support the timber workers. In November, the governor came to Duluth to help with negotiations after a standoff between logging trucks and the union picket line blockaded Highways 45 and 61 near Duluth. A deal was reached on November 21, and timber workers were able to keep the gains they had made in January.

The union succeeded in creating solidarity between poor people in northern Minnesota, not only between farmers and timber workers but also across racial and ethnic lines. The union was first led by two American Indian men, Fred Lequier and Jim Rogers. Finnish Americans like Ilmar Koivunen and Martin Kuusisto later led the union, and Jewish Americans Sam Davis and Irene Paull founded the union's newspaper, The Timber Worker. The union kept a united front even after it left the AFL to join the competing Congress of Industrial Organizations (CIO).

Although the logging industry was on its last legs in 1937, the timber workers' union used the labor movement's momentum and the support of a Farmer-Labor governor to significantly improve working conditions during the industry's final years.

Logging northern Minnesota was a difficult job — many loggers blew off steam by drinking, gambling, or visiting brothels. "Sky pilots" tried to save the men's souls and put them on the road to holiness rather than vice.
